Ubuntu 20 seems only have "*-live-server-* now. xCAT needs to start to verify the newer ubuntu version.
The installation should not be interrupted with the prompt. how did u kick off install? rinstall or nodeset ? you should use rinstall . it combine three command: nodeset, rsetboot and rpower If you want to modify the config file, you should write a postscripts. current xcat code didn't disable the SSH login for ubuntu. Use postscripts maybe more simple to replace source.list. The other method you can add those `http://` links to osimage's pkgdir. each dir in the pkgdir will be added to source.list.

I downloaded and deployed the "*18.04.5-server-*" ISO and the installation worked. My suggestion would be to amend the documentation warning users that for the purpose of xCAT, they should NOT get "*18.04.5-live-server*" ISO image. This is because somehow Ubuntu makes it much easier to find the "*-live-server-*" ISO as opposed to just "*-sever-*". I'm saying this from my own experience - if you google something obvious like "ubuntu server download iso 18.04" and follow the links, you'll eventually land on https://releases.ubuntu.com/18.04.5/ which presents links to the live ISOs only. I took a bit of time to look into the installed system and I have some questions: The installation the process is interrupted with a prompt "Install the GRUB boot loader on a hard disk". The prompt asks the users to specify a path to the drive where the boot loader should be installed. Is this working as designed? If yes, how can I eliminate this prompt in order to make the installation fully automatic, like CentOS? As it is customary with Ubuntu, password based root SSH login is prohibited by default. Is there a way (a postscript?) that can be used to unlock that in /etc/ssh/sshd_config (yes, I know about all the security implications, but for the purpose of this environment I don't care). I can right my own postscript, but I was wondering if one already exists, or if, perhaps, there is a method already built into xCAT. Don't want to spend time solving problem if it's already solved. The /etc/apt/source.list appears to be pointing to the xCAT repository, instead of the original Ubuntu repos (ex http://us.archive.ubuntu.com/ubuntu). But because the image on the xCAT server is a lean one (not much software in it), most of the packages one may want to install are missing from it. I fixed that manually by overwriting the sources.list with a copy from another Ubuntu server and got apt-get working. Is this an Ubuntu installer thing or an xCAT issue? How can I make sure that apt is pointing to the internet sources instead of the local ones? Should I write a postscript or there is a better way? Thanks a lot, Michael P.S. https://sourceforge.net/p/xcat/mailman/ shows "Oh snap! We can't process this request." this morning for me. I couldn't search mail list archives to find answer to my questions above.
